Of course, that brings up the ageless question: what controller to buy??
My needs:
6+ relays
Reliable.
Salinity probe (to check on water exchange)
temp monitor
Ethernet connection, to log and send warnings.
PH is not really needed, but nice, and usually included.
ORP would be fun, as a way to track sudden changes
Fishbit:
Fun, but not really available yet.
Strangely quiet since Beta went out a few months ago.
No track record.
ReefAngel:
Fun, low cost.
Needs lots of add on modules. (Flexible+ but Annoying-)
Nice mini graphic display.
Really programmable.
I had one before I went DIY. Still have parts of it.
But I am tired of Arduino.
Seneye:
Really only adds ammonia. Which is a non-issue.
Not really a controller.
Apex:
Well integrated, tons of support and options.
Simple and boring. Good quality. Just works.
Expensive.
Could use a nicer display.
Reefkeeper:
Medium cost. Needs lots of modules. Networking support needs work.
A lot like ReefAngel, but more expensive, not as programmable, and no nice display.

So for me, it comes down to ReefAngel versus Apex.
A whole lot like deciding between a Linux PC and a Mac.
And since I work at Apple ....
